Application filed September 29, 1927. SerialNo. 222;?(56.

This invention relates broadly to Aa con.

A further object otthis invention ther provision ot a knew, construction for accomplishing this purpose which employs extensible members suc-h as rubber strands or cords for absorbing such shocks.y n

A :further object ofthe invention is the provision ot a construction permitting relative movement 'betweenthe axles and chassis of the vehicle against the resistance ot a plurality of rubber strands.r

A still urtherobject of to provide ay construction for these purposes which is relatively cheapand simple to inanufacture but neverthelessv rugged in construction and adapted iforlon'g-use.l i Thesepand inanyjotherkob'ects as will ap-L pear from the description are successfully sought by means ofthe following construc-- tion.

'y This invention residessubstantially the combination, construction7 arrangement and relative location of parts as will appear 4in the following description when taken in conjunction with the drawings.

c Referring tothe drawings,

Figure l is aside elevational view ofthe' construction yei'iiployed in this'y yinvention showing the side chassis members in cross section.

Fig. 2 is an enlarged side elevational View Y of the suspension members,

4In the usual constructionot vehicle suspensiondevices,such tor instance as the well known elliptical spring constructiom it isy found, that insteadoif' absorbing shocks due to the movement ofthe vehicle over theroad,

there is a tendency only to deflect theloodyA oit the vehicle rather thanto absorb'the shocks.v

The result is that the vehicle body is violently thrown 'from side'to sideor upwardly when the wheels encounter rough spots in the road so that the Whole vehicle is subjected toundue stresses andstrainyswhich cause a rapid deterioration of the parts.y ,There is also atendency for the spring structure to be shat-y tered. lt is the purpose fof this invention to` p provide a construction which issuitable for,

vehicle over une-ven this invention is use onpassenger 'vehicles as wellas heavy trucking vehicles which will absorbgfthe shocksr rather than deflect them;

ln the construct/loiret this invention itis f proposed tofemploy a plurality rubber strandsr or ,other suitable yextensibleelements which will truly absorb the shocks Without transmitting them tothe body off the vehicle.

It is7` oil course,frecogni7ied thaty rubbericords.` ror strands have been used before for a simi-r lar purpose. This invention however relates to a particular construction ywhich provides f a parallel ymeansiwforr4 employing rubber strands tor supl'oorting` vehicle bodies.v s

- Referringto the drawings in F ig.` l there 1s shown the road wheels 1 and the usual brake bands 2 whichy are mounted on the axle 9 (Fig. 2) which' extends ythrough thehollow casing 4t, the dillerential being shown inFig.

r'lhesidenieinberslot the chassis areshown at 3 and are arranged to'rest inthe L-shaped j formation of the brackets 6 which are secured n .thereto` and dependtherefrom. The brackets are arranged inpairs, twopairsbeingplacedk on each side "of the chassis as willy be' readily understood. `rThe lower ends ofthe brackets yextend horizontally and. at right angles to their inainportionand are fpro`r vided attlieir endswith vertical slots,l fThese 7 d5 horizontal extensions are presented toward each other but are separated somewhat. The

y axle receivinginelnber is shown'at 8 comprisi ing two partswhich aie securedtogether ,byL a number of bolts 10. Each of these parts has ax `vertically extendingrib 7 which rare arrangedinther slots at the horizontal ends of ythe bracket 6 and .which `have been indicatedby the referencenumerals 9. 'lhe'upper ends fot theineinbers 81 are provided with hori-y Zontal extensionsll as shown in Fig. 2. HOL' lowsocket members are shown at 12 and are formed integral ywiththe bracket 6. Afsingle length ot rubber rope or strand is shown as comprising'a pluralityy of turns 14;y which `are wrapped aroiuidjtlie horizontal portions 9 of the bracket 6 and the. extensions 11 of the y nienibers 8. Lrlheflengths 'oftherubber cord are secured in the sockets k12 by means of tapered wedges `1S.ltispointed out `thatfthe y specific clanipingfineans when taken alone, 'formsno part 'of this invention,

I From the 4foregoing descri ati thepltirality effetrandsret rubber on it lwill be d apparent that the vehicle bodyland chassis are y .y

supported on thewheels and axle by means ot v y which are Vunder tension. iWlieiiever Lthe Wheels oit the vehicle strike an unevenness in the ground they will tend to rebound-np- `wardly carrying vthe .construction comprising the members *Svertical'ly upward; against the resistance Aoi2 the rubber strands 14. rhe relative movement between -the vviiiienibers `8 and the bracket 6'is guided by reason ot the fact that the rib members 7 are arrangedto vslide in theslots inthe end of the horizontal vvportions '9 otliebi-.acket 6.

' From the 'foregoing description it willbe :apparent that 'I have deviseda relatively sim- AIple coi'istructionfor carrying out the purposes "ot' ythisinvention. While-d have shown one ,embodimentiotthe'inventioninthe draivi 0" 1D) I wish itftojbe understood that there are many clianges'in the details Voiicoiistruction and relative A.zirrangement of Lparts as will be `readily,apparent to thoseskilled in the art tand 'I donot desire therefore, to vbe 'limited except asrequired by the appended claims.
